i wanted to change the sparkplugs on my 1994 Buick Century V6 just because I never have in 5 yrs.
There are 3 spark plugs in the rear of the engine block and 3 in the front.
I pulled all 3 wires on the side closest to the front of the car and now I do not know the proper order? I've tried a few combinations and the engine sounds terrible.
Please help me get this in the right order before I break something! The cables are marked 2, 4, and 6. thx
